当用户选择要显示以下错误的联系人时,尝试在给定的tableView中显示与预建UI的联系人:
CNPropertyNotFetchedException',原因:'联系人0x7fded8ee6f40是 缺少一些必需的键描述符:[CNContactViewController descriptorForRequiredKeys] GT;
我已经尝试通过这种方法解决:Contact is missing some of the required key descriptors in ios
所以我的联系人数组创建如下:
func searchContactDataBaseOnName(name: String) {
results.removeAll()
let predicate = CNContact.predicateForContactsMatchingName(name)
//Fetch Contacts Information like givenName and familyName
let keysToFetch = [CNContactGivenNameKey, CNContactFamilyNameKey, CNContactViewController.descriptorForRequiredKeys()]
let store = CNContactStore()
do {
let contacts = try store.unifiedContactsMatchingPredicate(predicate,
keysToFetch: keysToFetch)
for contact in contacts {
self.results.append(contact)
}
tableContacts.reloadData()
}
catch{
print("Can't Search Contact Data")
}
}
当用户点击行索引时,我试图通过这样做来显示:
func tableView(tableView: UITableView!, didSelectRowAtIndexPath indexPath: NSIndexPath!) {
let viewControllerforContact = CNContactViewController(forContact: results[indexPath.row])
viewControllerforContact.contactStore = self.contactStore
viewControllerforContact.delegate = self
self.navigationController?.pushViewController(viewControllerforContact,animated:true)
}
关于如何解决的任何想法?似乎我仍然缺少将descriptorForRequiredKeys传递给数组“结果”......也许?
答案 0 :(得分:3)
你正在获取所需的密钥并将它们存储在你正在调用的结果变量中,所以我不知道原因。您可以使用所需的密钥重新获取联系人以解决错误:
var contact = results[indexPath.row]
if !contact.areKeysAvailable([CNContactViewController.descriptorForRequiredKeys()]) {
do {
contact = try self.contactStore.unifiedContactWithIdentifier(contact.identifier, keysToFetch: [CNContactViewController.descriptorForRequiredKeys()])
}
catch { }
}
let viewControllerforContact = CNContactViewController(forContact: contact)
